MediaWiki Testing

Wednesday, 13 May 2009

With regret I have to announce that the collaboration with Wikiation has come to an end. The root cause are difference of opinion on how an Open Source project is to be run. Wikiation has been very important in the development of the software and this is something we do acknowledge. However there was no effective appreciation for all the work that was done for free and sadly the software did not get enough of a practical application because of directions by Wikiation.

As Wikiation has pulled out of the project and as it has indicated that its name should not be associated with our continued development, the software will now be called "MediaWiki Testing Environment". It is no longer called an "Extension Testing Environment" because it is not only extensions that get tested by the software.

We are now preparing this conversion and, we are preparing the integration of the running of test cases in the MediaWiki Testing Environment.

We expect that we will have more positive news for you in the future.
Thanks,

Yesterday I had the pleasure of presenting the extension testing environment to people of the Wikipedia Usability Initiative (UI). It was a pleasure because many of the requirements for the UI can be met by our environment.

What we discussed and/or demoed:

the motives for the Wikiation Extension Testing Environment

testing on different operating systems and (LAMP) configurations

the need for the creation and duplication of test environments

the need for testing environments with different configurations for instance with and without flagged revisions

I am building he WikiEducator test environment and as I mentioned in a previous blog, several of the extensions exist as a text source somewhere on a Wiki. This was also true for WikiArticleFeeds. I am really happy that the developer of WikiArticleFeeds has submitted it to the WMF SVN.

Having WikiArticleFeeds in the WMF SVN, is the first step of Open Source magic. I asked on IRC, the mediawiki-i18n for support and half an hour later an intenationalisation file had been added by IAlex. It is now ready to be supported on translatewiki.net.

I have asked other WikiEducator developers to help me out. The response so far has been great. I love such Open Progress.
Thanks,

WikiEducator is where the Commonwealth of Learning has an excellent project for free e-learning content; I rate it as best of breed. As the Commonwealth of Nations consists of many countries in all parts of the world, WikiEducator has to take into account the many different cultures in order to provide quality education.

it is not clear if there have been modifications to the code in the past

Even though it is not that hard to create a new extension in the WMF SVN, it is best when this is done either by the developers or by the people behind WikiEducator. When asked typically there is a positive response.

A special case is the LiquidThreads extension. This extension is broken in its latest revision. The testing environment makes it really easy to establish this or to find what effect other extensions have. The COL and Unicef are collaborating, it is fairly trivial to install and test the Uniwiki extensions in a combined environment as well.

The current incarnation of the WikiEducator testing environment can be found here.
Thanks,

Jmol is an extension I blogged about in the past. What Jmol does is show what chemicals, proteins look like. It does not only do a good job visualising, it really lightens up pictures that are otherwise rather dull.

Installing Jmol proved to be interesting, it has a prerequisite called StubManager. This is a tool that is essential for a whole range of extensions and it is required to be installed before all the tools that make use of it.

Jmol itself was interesting as well; it installed itself in a directory called MediaWiki and ia directory with java stuff. For the Wikiation Extension Testing Environment, we are looking for a standard way of installing the stuff because that also allows for clean un-installs. Everything is now in the Jmol directory, we now only have to make it work.
Thanks,

When you test an installer, you need to test the installation of extensions. I made the choice to build copies of MediaWiki environments. My assumption is that the functionality of great environments is what would be of interested to many people.

Referata provides a best practice environment for Semantic MediaWiki. Yaron, the man who runs Refarata is also behind many of the Semantic MediaWiki extensions. Obviously the secret sauce of Referata is Yaron's ability to fix whatever comes his way.

I informed Yaron about the test environment, we found some issues and he fixed them for us.

The Wikiation Extension Testing Environment has so far concentrated on server side issues. How do we install MediaWiki, how do we install extensions, how do we run tests serverside. The tests we currently run are parser tests and tests run using the pywikipedia framework.

This is all really nice but the proof of the pudding is in the eating and this is done with browsers. Given our values, tools to do the testing need to be freely licensed as well.

The great thing about Selenium is that it already has many add ons to do serious testing. It allows for automated testing for multiple browsers. It allows for using a grid of systems to do the testing. To me it looks exactly right. I asked MinuteElectron to look at it as well; he is really entheausiastic, he started to convert his work on Uniwiki into Selenium already.
